| titleOfInvention | System for broadcasting audio-visual television signals synchronized by a pilot frequency and method for the application of said system |
| abstract | ABSTRACT OF THE DISCLOSURE A system for broadcasting audio-visual signals representing television pictures defined by fields, each field divided into scanning lines, the audio-visual signals including a video signal component; the system comprises: a recording section including a first frequency-modulation circuit for producing a carrier wave modulated by the video signal component, a second circuit for producing a continuous sine wave signal having a frequency that is a multiple of the line scanning half frequency of the pictures, a third circuit for combining the carrier wave, as modulated by the video signal component with the continuous sine wave signal for producing a composite signal, a fourth cir-cuit for width-modulating and amplitude-limiting the composite signal, an information medium provided with a track for recording the composite signal, and a reading section comprising: filter circuits for extracting the continuous sine wave signal from the composite signal and means for generating synchronizing signals from the continuous sine wave signal. |
